The Intel Core i9 10900K was launched in the second quarter of 2020. Based on a 14nm lithography i.e. the semiconductor technology used to manufacture an integrated circuit, and is reported in nanometers. The Intel Core i9 10900K is a 10 core processor with 20 threads with a base frequency of 3.70GHz and a boost frequency of 5.30GHz. The newer Intel Core i9 11900K was launched in the first quarter of 2021. The newer processors come in the same 14nm lithography but have a reduced number of cores and threads. The Intel Core i9 11900K is an 8 core and 16 thread processor with a 350GHz base frequency and a boosted frequency of 5.30GHz. Another major upgrade for the Intel Core i9 11900K was the support of DDR4 3200MHz memory modules while the Intel Core i9 10900K was locked at DDR4 2933MHz memory modules.
For this comparison, we are going to test them in terms of the FPS of the Intel Core i9 10900K produced in games against the FPS produced by Intel Core i9 11900K in 1080p and ultra settings. The single-core and multi-core performance in benchmarking applications will also be tested to see which one is faster. For the test, we are going to use an Nvidia Geforce RTX 3080 for the test to prevent any bottlenecks
Firstly In Shadow of the Tomb Raider, we don’t see a major difference in FPS. The Intel Core i9 11900K is just 2-3% faster than 10900K which is not a huge difference. Both the average FPS and the minimum FPS were over 100 frames per second and performed similarly.
Next in CYBERPUNK 2077, the difference between the average and minimum FPS was the same as before. The Intel Core i9 11900K performance was 2-3% faster than the 10900K in average FPS. However, the minimum FPS was 2-3% higher for the Intel Core i9 10900K. This made no significant visual difference.
In Microsoft Flight Simulator the changes in both the average and minimum framerates were visible and can be noticed. The average FPS of the Intel Core i9 11900K was 7-8% higher than the Intel Core i9 10900K while the minimum FPS of the Core i9 10900K was 30-40% higher which was a significant boost over the Intel Core i9 10900K in terms of FPS.
Even in Call of Duty Warzone the Intel Core i9 11900K was 7-8% faster in average FPS as well as in the minimum FPS from the Intel Core i9 10900K giving it a slight improvement in FPS.
But in Red Dead Redemption 2 we can see that the Core i9 10900K was able to compete with the Intel Core i9 11900K head to head. The Average FPS and minimum FPS of both the processors were similar. We could see that the new generation of processors was not providing any additional framerates.
In Cinebench R20 the single-core performance of the Intel Core i9 10900k and 11900K was pretty similar in terms of benchmark scores but in the multi-core performance the Core i9 10900K was almost 2% faster than the Intel Core i9 11900K.
Even in Geekbench 5, the Intel Core i9 11900K was almost 20% faster in the single-core test than the Intel Core i9 10900K. The Intel Core i9 11900k’s multicore performance was ahead in the multi-core test but by a smaller margin.
From the above benchmarks here we conclude that the newer 11th gen Intel Core i9 11900K was not a major upgrade over the Intel Core i9 10900K. In most of the tests, the scores were similar in terms of FPS and benchmark reports. So if you are going to pick up either of these processors it will be a good choice and you should pick the one you get cheaper since the performance was similar.
